The two-dimensional Graphene has the perfect crystal structure, its lattice consists of six carbon atoms surrounded by hexagons, and thickness of an atomic layer. Connected by bonds between the carbon atoms, combined with the way SP2 hybridization, these bonds give Graphene excellent mechanical properties and structural rigidity. Graphene's 100 times stronger than the best steel hardness, even more than diamonds. In Graphene, each carbon atom has a p that is not bonding electrons, these p electrons can move freely in the Crystal, and moving at speeds up to the speed of light in 1/300, giving good conductivity of Graphene. Graphene is the next generation of transparent conductive material in the visible range, four-layer Graphene through rate comparable with conventional ITO Film, among other bands, the penetration rate is much higher than the four-layer Graphene ITO thin films.
Graphene is the thinnest in the world, the most known of hard nanomaterials, it is almost completely transparent, just 2.3% light up to 5300W/m thermal conductivity · K, than carbon nanotubes and diamond at room temperature electron mobility than 15000cm2/V • s, than carbon nanotubes or silicon high resistivity around 10-6 ω · cm, lower than copper or silver, which is the world's smallest material resistivity. Because of its very low resistivity, electron transfer very quickly, and so are expected to be used for the development of more thin, conductive faster, next-generation electronic components or a transistor. Since Graphene is essentially a transparent and a good conductor, also suitable for making transparent touch screens, light, and even solar cells.
